[不定项选择题]共用题干 The Interpersonal Skills of Children Without Siblings

Many parents may think that each new sibling(兄弟姐妹)offers their children the gift of companionship.But while we tend to think that siblings teach one another conflict resolution and other interpersonal skills,new research says they are no better off socially than children without siblings.
"Most studies look at the negative consequences of having siblings in terms of educational outcome,"said Donna Bobbitt-Zeher,lead author of Good for Nothing?Number of Siblings and Friendship Nominations Among Adolescents."But we decided to look at social skills to see if there was any other possible benefit to having brothers or sisters."She and her co-author,Douglas Downey are sociologists at Ohio State's Marion campus,and neither is an only child.They presented their findings at the annual meeting of the American Sociological Association in August.
The paper is in large part a reply to a previous study,Playing Well With Others in Kindergarten:The Benefits of Siblings at Home,also co-authored by Dr. Downey,which found that kindergarten teachers rated children without siblings worse in interpersonal skills,self-control and problem behaviors.
But an only child isn't necessarily a loner and misfit.First,the social advantages found in children with siblings in the kindergarten study were quite modest.Second,the study relied on teacher evaluations,and teachers may not be reliable judges of friendships among their charges.
And now it seems that any benefits documented in kindergarten disappear altogether by middle school. Using a metric called"peer nomination(提名)",Dr. Downey and Dr. Bobbitt Zeher found that children without siblings had just as many friends as,children with siblings.
"I see the two studies as a natural progression,showing what happens to the only children who didn't have much interaction before kindergarten,"Dr. Downey said.Another study he is working on shows that the same only children evaluated in kindergarten had caught up by fifth grade.
While the studies don't examine the cause for the disappearing social boost to kindergartners with siblings,Dr. Downey speculates that continuing school,youth clubs and other group activities一especially in an era of overscheduled children一provide sufficient opportunity for onlys to sharpen their skills. Kindergarten teachers' evaluation may be________.
A.helpful to improve the only childrens' social skills
B.better than the only childrens'
C.beneficial to children in any other ways
D.complete
E.unfair
F.unnecessary
